Sara is asked to create a controller for light sensors. When the light falls on the sensor, it needs to indicate when a particul
ar object is moved from its original position. For this, she needs a credit card-sized motherboard with a microcontroller on it. Which option should she select?
<em>Arduino is a free and open-source electronics platform with simple hardware and software. Arduino boards can read inputs, turn on a sensor and transform it into an output, activate a motor, and turn on an LED. Sara may direct her board by sending a series of instructions to the board's microcontroller. To accomplish so, she used the Arduino programming language and the Arduino Software (IDE), both of which are founded on Processing.</em>
